4. First Aid Measures

Inhalation: Move to fresh air, seek medical attention if irritation or symptoms persist
Eye Contact: Rinse immediately with plenty of water for several minutes; remove contact lenses if easy to do
Skin Contact: Wash with soap and water, remove contaminated clothing, seek medical aid for persistent irritation
Ingestion: Rinse mouth, drink water if conscious, avoid inducing vomiting unless directed by medical advice

5. Fire-Fighting Measures

Suitable Extinguishing Media: Use water spray, foam, dry chemical, or carbon dioxide for surrounding fire
Unsuitable Media: Avoid high-pressure water jet if possible
Special Hazards: Product is not flammable or explosive; may emit metal oxides in a fire
Protective Equipment: Self-contained breathing apparatus and protective clothing recommended for firefighters
Thermal Decomposition Products: Metal oxides such as vanadium oxides and bismuth oxides

6. Accidental Release Measures

Personal Precautions: Wear eye protection, gloves, and a dust mask or respirator if dust is generated
Environmental Precautions: Avoid spills into drains and surface water; minimize environmental exposure
Clean-up Methods: Use wet cleaning methods or vacuum with a HEPA filter; avoid creating dusty conditions, transfer to a closed and labeled waste container
Disposal: Dispose of as described in section 13

7. Handling and Storage

Handling: Use local and general ventilation to minimize dust exposure; wear proper personal protective equipment
Safe Practices: Avoid eating, drinking, or smoking in areas where material is handled; wash hands after use
Storage Conditions: Store in a dry, well-ventilated area, away from food and feedstuffs, keep tightly sealed in original containers
Incompatible Materials: Strong oxidizing or reducing agents may react with components

8. Exposure Controls and Personal Protection

Occupational Exposure Limits: No established TLV for Bismuth Vanadate itself, but ACGIH/TLVs for nuisance dust (10 mg/m³ total dust, 3 mg/m³ respirable)
Engineering Controls: Use local exhaust ventilation to control airborne dust
Personal Protection: Dust mask or respirator for dusty conditions, safety glasses, protective gloves
Hygiene Measures: Wash hands and skin thoroughly after handling, change and wash contaminated clothing regularly

9. Physical and Chemical Properties

Appearance: Yellow powder or pigment
Odor: Odorless
Odor Threshold: Not applicable
pH: Not applicable (insoluble in water)
Melting Point: Decomposes above 850°C
Boiling Point: Not applicable (decomposes before boiling)
Flash Point: Not flammable
Evaporation Rate: Not applicable
Flammability: Non-combustible
Vapor Pressure: Not relevant
Density: About 6.5 to 7.0 g/cm³
Solubility: Insoluble in water and most solvents
Partition Coefficient: Not relevant
Decomposition Temperature: >850°C
Viscosity: Not applicable

10. Stability and Reactivity

Chemical Stability: Stable under usual conditions of handling and storage
Hazardous Decomposition Products: May produce bismuth and vanadium oxides at temperatures above decomposition
Reactivity: Not reactive under standard conditions
Incompatible Materials: Strong oxidizing or reducing agents
Conditions to Avoid: Extreme heat, formation of excessive dust

11. Toxicological Information

Acute Toxicity: No acute toxicity evidence for the compound; low absorption expected due to insolubility
Skin Corrosion/Irritation: May cause mild mechanical irritation
Serious Eye Damage/Irritation: Particulates can cause physical irritation
Respiratory Sensitisation: No known sensitizing properties
Chronic Effects: Long-term health effects unlikely at occupational exposures; vanadium compounds may present greater risks if bioavailable, but Bismuth Vanadate is poorly soluble
Carcinogenicity: Not listed by IARC, NTP, OSHA
Mutagenicity and Reproductive Toxicity: No significant evidence in public literature for Bismuth Vanadate

12. Ecological Information

Ecotoxicity: Not expected to be harmful in usual discharge quantities due to insolubility; aquatic toxicity studies show minimal acute hazard
Persistence and Degradability: Inorganic compound, unlikely to degrade, remains indefinitely in the environment without transformation
Bioaccumulation Potential: Expectedly low due to poor solubility in water
Mobility in Soil: Very low, since it does not dissolve or move with water
Other Adverse Effects: No specific concerns for Bismuth Vanadate in standard use; minimizing dust and waste release always makes sense for all inorganic pigments

13. Disposal Considerations

Waste Disposal Methods: Dispose of in accordance with local, regional, and national regulations; landfill disposal is typical for insoluble inorganic pigments
Contaminated Packaging: Rinse and dispose of packaging according to legal requirements
Special Precautions: Do not release in unprocessed form to waterways or drains; collect dusts and residues in labeled waste containers

14. Transport Information

UN Number: Not classified as dangerous goods under UN, ADR, IMDG, or IATA regulations
UN Proper Shipping Name: Not regulated
Transport Hazard Class: Not hazardous
Packing Group: Not applicable
Environmental Hazards: Not a marine pollutant
Special Precautions: Protect packaging from being punctured; keep dry during transport to prevent caking
